SASH-FASTENER.

SPECIFIC ATION forming part. of Letters Patent No.314,162, dated March 17, 1885.

Application filed May 24, 71884. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN ASHTON, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Sash-Fasteners, of which the following is a specification.

My invention consists of a sash-fastener constructed in the manner described and claimed hereinafter, with the view of locking both sashes in any desired position and of preventing the unlocking of the sashes by an instrument inserted between them.

In the accompanying drawings,Figure 1 is a sectional viewshowing parts of the upperand lower sashes of a window with my improved fastener, the sashes being unlocked; Fig. 2, the same showing the sashes locked; Fig. 3, a perspective view of the fastener; Fig. 4, a transverse section of the same, and Figs. 5 and 6 views showing modificationsof part of theinvention.

A and B are the meetingrails of the two sashes, and D the center bar of the upper sash. To the rail A of the lower sash is secured a casing, F, in the opposite sides of which are bearingsi'or a transverse pin, a, which carries an eccentric, b, the outer ends of the pin being secured to a yoke, (I, which embraces the casing, the top of the latter being semicircular, so that the yoke is free to swing over the same. Y To the eccentric b is fit-.

ted a sleeve, f, forming part of a bolt, 9, which is guided in an opening in the casing F, and

when projected is adapted to enter any one of a number of openings, m, in the bar 1) of the upper sash, these openings lelng surroundtd by suitable metal plates, n, to prevent wear; \Vhen the yoke (Z is in the position shown in Fig. 1, the bolt 9 is retracted and the sashes can be moved freely; but when the yoke has been moved to the position shown in Fig. 2 the bolt is projected so as to enter one of the openings m, and thus prevent movement of either of the sashes to open the same, the accidental displacement of the yoke being prevented by a spring-retainer, p, on the top of the casing F. The bolt cannot be forced back by an instrument inserted between the sashes, as the thrust is almost directly in line with the pivot of the eccentric, so that the latter cannot be turned without the exercise of great eii'ort. The use of the eccentric b is not essential to my invention, however, as the bolt vg may be operated by an arm on the pin a, as

in Fig. 5, or by rack-and-pinion device, as in V Fig.. 6, the eccentric being, however, preferred. The casing F may be located at one side of the sash, or casings may be used at both sides of the sash, if desired, the openings m in this case being made in the side bars of the upper sash, instead of in the center bar,

and where it is desired to simply look the device carried thereby, and the yoke d, as set forth.

2. The combination of the sashes, the bar D, having an opening or openings, m, the easing F, the bolt g, the shaft a, the eccentric .b, and the yoke d, as set forth.

In testimony whereot'l have signed my name.

to this specification in the presence of two subscribing witnesses.
